[0001] This utility model relates to the field of LED display technology, specifically to an LED screen cabinet frame with a control box and an LED display combination screen. Background Technology

[0002] Currently, large outdoor LED displays have various applications, such as advertising displays and rental displays. Among them, rental displays are usually rented in various locations, which inevitably requires frequent moving, disassembly, and installation. Therefore, for easy handling, they need to be made into a thin and light structure. At the same time, for easy disassembly and assembly, they need to adopt a structure that is easy to disassemble and assemble, and also to save time and facilitate operation.

[0003] Existing LED display cabinet frames typically use a main frame to house one or more control boxes. Usually, one LED display module corresponds to one control box. Therefore, a number of control boxes are usually required to control each LED display module. During installation or maintenance, each control box is frequently disassembled and maintained, which is relatively time-consuming. Moreover, a large number of control boxes also occupy space covering the back of the cabinet frame, making it difficult to apply to ultra-high perforation and high transparency displays.

[0025] As shown in the figure, the LED screen cabinet frame with control box 100 provided in the embodiment of this utility model includes a cabinet frame body 50 and a control box 100; the control box 100 is mounted on the back 510 of the cabinet frame body 50, the cabinet frame body 50 includes multiple side frames 51 and a middle frame strip 52; the middle frame strip 52 is connected between two parallel side frames 51, and the middle frame strip 52 is provided with a receiving groove 521; the control box 100 includes a top cover 101, a HUB board 53, and at least one power supply 55; the HUB board 53 is mounted in the receiving groove 521 of the middle frame strip 52, the HUB board 53 includes multiple signal interfaces, the power supply 55 is mounted inside the top cover, and the middle frame strip 52 and the top cover define a cavity to accommodate the HUB board 53 and each power supply 55.

[0026] Specifically, the outer wall 523 of the receiving groove 521 has a plurality of first mounting portions 524, and the upper cover 101 is provided with a plurality of second mounting portions 104 respectively assembled with the plurality of first mounting portions 524. In some specific embodiments, the plurality of second mounting portions 104 are a plurality of buckles 10, and the plurality of first mounting portions 524 are a plurality of fasteners, with each buckle 10 corresponding to one fastener.

[0027] like Figure 3 As shown, preferably, a plurality of the first mounting portions 524 are symmetrically arranged on the outer sides of the groove edges of the outer groove wall 523 of the receiving groove 521; the groove length of the receiving groove 521 is slightly less than the length of the middle frame strip 52, that is, it is just long enough to avoid the distance between the upper and lower locks installed on the main body of the cabinet frame 50 at both ends. By setting such an extra-long groove, the entire integrated HUB board can be accommodated. The integrated HUB board is suitable for the overall control of the entire LED display combination screen, that is, the integrated HUB board is provided with signal interfaces corresponding to the multiple LED display modules. Of course, one LED display combination screen in the figure can also be regarded as a unit, and a super-large LED display screen can be assembled from multiple LED display combination screens shown in the figure.

[0028] Preferably, the middle frame strip 52 is provided with a third mounting portion 525; the third mounting portion 525 includes a mounting hole integrally extending from the side edge of the middle frame strip 52, similar to an ear hole. A pin or fastener passes through the mounting hole and the pin hole 615 on the back of the LED display module 61.

[0029] like Figures 4 to 6As shown, each of the latches 10 further includes an upper fastener 11, a mounting base 20, a first pivot 31, a limiting plate 40, and an elastic member 24; the upper fastener 11 is mounted on the mounting base 20 via the first pivot 31, the elastic member 24 has a first end and a second end, the limiting plate 40 is disposed between the first end of the elastic member 24 and the first pivot 31, the second end of the elastic member 24 abuts against the latch body, the upper fastener 11 has a fastening portion to be able to be fastened to the fastening position, when the upper fastener 11 is fastened to the fastening position, the elastic member 24 is in a compressed state, and after the upper fastener 11 is released, the elastic member 24 acts on the limiting plate 40 to restrict the first pivot 31.

[0030] Specifically, at least one power source 55 is two or more power sources 55, each of the power sources 55 is arranged side by side along the length of the middle frame strip 52, and each power source 55 has a set of first connectors 551; the HUB board 53 is provided with a set of second connectors 531 on the side facing the top cover, and the first connectors 551 and the second connectors 531 are arranged in a row of male and female plug-in structures.

[0031] like Figures 4 to 6 As shown, in some specific embodiments, the upper cover 101 is provided with a fan 18, a signal test adapter board 59, a test button 58, a vent valve 57, a power connector 553, and a signal connector 556. There are two fans 18, each corresponding to the position of the power supply 55. The signal test adapter board 59 is mounted on the inner top wall of the upper cover 101. The test button 58 is mounted on the upper cover corresponding to the signal test adapter board 59. The vent valve 57 is located at one end of the upper cover 101. The power connector 553 and the signal connector 556 are mounted side by side on one end face of the upper cover 101.

[0032] In some preferred embodiments, the middle frame strip 52 serves as the bottom cover of the control box 100. The bottom cover or the inner bottom wall 533 of the receiving groove 521 is configured as a HUB connection plate. The side of the HUB plate 53 facing the receiving groove 521 is provided with multiple sets of signal connectors 532. The bottom wall 533 of the HUB connection plate is provided with multiple sets of third connector holes 511. The multiple sets of third connector holes 511 correspond to the multiple sets of signal connectors 532 of the HUB plate 53. Each third connector hole 511 protrudes towards the LED screen, and the edge of each third connector hole 511 is waterproofed by a rubber plug 515. The middle frame strip 52 is provided with multiple magnet mounting holes 516 on the side facing the LED screen and in each frame 51. Each magnet mounting hole 516 is equipped with a magnet for magnetic mounting to the LED screen.

[0033] Specifically, multiple LED display modules 61 are arranged in an array on the front of the housing frame.

[0034] When the buckle 10 is in use, the limiting plate 40 is held against the first rotating shaft 31 by the elastic element. When the upper fastener 11 is released from the buckle position, the elastic element will continue to hold against the first rotating shaft 31. On the one hand, it can push the first rotating shaft 31 away from the buckle position, and on the other hand, it can also limit the rotation of the first rotating shaft 31 to a certain extent, so as to prevent the upper fastener 11 from falling back and maintain a relatively upright position, which facilitates the next buckle installation operation.

[0035] In some specific embodiments, such as Figures 4 to 6 As shown, the mounting base plate 20 includes a base plate and two side plates 22 disposed on both sides of the base plate. The two side plates 22 are respectively provided with V-shaped grooves or V-shaped holes at opposite positions. The two ends of the first rotating shaft 31 are respectively disposed in the V-shaped grooves or V-shaped holes of the two side plates 22. The two ends of the first rotating shaft 31 are respectively provided with protruding rings, each of which is engaged outside the V-shaped groove or V-shaped hole. The first rotating shaft 31 can slide back and forth along the V-shaped inclined wall of the V-shaped groove or V-shaped hole. In this embodiment, the V-shaped groove 27 is shown in the figure. On one hand, it provides guidance and space for the first rotating shaft 31 to move back and forth; on the other hand, it provides vertical space for the first rotating shaft 31, thus giving the upper fastener 11 considerable flexibility and freedom when fastened downwards.

[0036] Preferably, the limiting plate 40 includes a vertical plate 41, a top plate 42, and two side baffles 43. One side of the vertical plate 41 abuts against the elastic member, and the other side abuts against the first rotating shaft 31. The top plate 42 is located above the first rotating shaft 31 to limit the upward movement height of the first rotating shaft 31. The two side baffles 43 are located on both sides of the elastic member. When the upper fastener 11 is active, the first rotating shaft 31 moves in the V-groove or V-hole. At this time, the limiting plate 40 provides the upper part of the first rotating shaft 31 with a top pressure and the forward elastic pressure, thereby limiting the upward movement space of the first rotating shaft 31 and the degree of suppressed (requiring overcoming the elastic force) movement towards the fastener. The two side baffles 43 can limit the predetermined space on both sides of the elastic member or limit the offset of the elastic member to both sides.

[0037] In some preferred embodiments, the elastic element is a spring 24, and there are two springs 24 arranged side by side. The mounting base plate 20 is provided with a stop at a predetermined distance from the first rotating shaft 31. The two ends of each elastic element act on the limiting plate 40 and the stop, respectively. Two side baffles 43 are located on both sides of the two springs 24. The two springs 24 can provide sufficient elastic force and are durable. At the same time, since the two springs 24 provide two forces in the same direction, the action is more stable and reliable when the two springs 24 act in the same direction at the same time. This provides strong retention for the locking and unlocking of the upper fastener 11 and the stable and reliable operation after unlocking, and brings a skillful, stable, convenient, safe and reliable user experience.

[0038] In some specific embodiments, the buckle 10 further includes a middle cover 35, the stop is a second pivot 32, the second pivot 32 is parallel to the first pivot 31; the two ends of the second pivot 32 are respectively mounted on the two side plates 22; the middle cover 35 has two lower edge plates 36, the two lower edge plates 36 are respectively attached to the outer side of the two side plates 22, preferably, the sides of the two lower edge plates 36 that are attached to the two side plates 22 are smooth surfaces. The two lower edge plates 36 are respectively provided with a front axle hole 37 and a rear axle hole 38. Each front axle hole 37 is an oblong hole, which has a predetermined length in the direction of the elastic force or in the direction of the upper fastener moving towards the fastening position, so that the upper fastener 11 can be pulled closer to the fastening position and retracted to provide a predetermined horizontal stroke. At the same time, the middle cover 35 itself is mounted on the mounting base 20 closer to the fastening position via the second pivot 32. The middle cover and its mounting structure enable it to cooperate with the upper fastener 11 in movement. For example, when the upper fastener 11 is released, the middle cover 35 will restrict the movement of the upper fastener 11 to a certain extent, because the middle cover 35 can only rotate around the second pivot 32. Meanwhile, the front axle hole 37 of the oblong hole provides a forward and backward movement stroke. The second pivot 32 passes through the two side plates 22 and is mounted in the rear axle hole 38; the first pivot 31 passes through the front axle hole 37; the front axle hole 37 is engaged with the inner side of the convex ring and the outer side of the side plate 22 of the mounting base 20. The upper fastener 11 has a pivot hole 116, and the front pivot hole 37 corresponds to the pivot hole 116, allowing the first pivot 31 to pass through. The mounting base plate 20 of the upper fastener 11 also has a fixing hole 201, through which the entire buckle 10 is mounted on the upper cover 101 of the control box 100 with fasteners.

[0039] In some specific embodiments, the upper fastener 11 has two rotating feet 15 extending rearward from one end. The two rotating feet 15 are rotatably mounted on the two first rotating shafts 31 respectively, and the two rotating feet 15 are in contact with the outer side of the middle cover 35. The fastening part is a fastening tongue 16. The fastening tongue 16 is located at the other end of the upper fastener 11 away from the rotating feet 15 and extends horizontally inward, that is, it extends inward parallel to the direction of the elastic force. Of course, it can also be appropriately tilted. The main purpose is to provide a firm grip so that the control box 100 is stably installed on the middle frame strip 52. Furthermore, the middle cover 35 has an upwardly extending rear stop 351. The middle cover 35 also has a lower extension 352 near the fastening position. The second end of the elastic element abuts against the lower extension 352. The lower extension 352 has a sleeve post 353, and the spring is sleeved on the sleeve post 353. The sleeve posts 353 are generally horizontally positioned or parallel to the extension direction of the latch tongue, and preferably there are two, each sleeved onto one of the two sleeve posts 353. The upper fastener 11 has a waist portion 115 located between the two rotating feet 15. The rear stop portion 351 protrudes from the body of the middle cover 35 at a height greater than the distance between the waist portion 115 and the first rotating shaft 31, so that when the upper fastener 11 is lifted, the waist portion 115 can rest against the rear stop portion 351. In this way, the waist portion 115 and the entire upper fastener 11 can rest against the rear stop portion 351 of the middle cover 35. Preferably, the rear stop portion 351 extends obliquely backward, so that the upper fastener can lean backward when resting, making it less likely to fall back into the fastening position.

[0040] Preferably, the control box 100 is mounted on the middle frame strip 52 via the buckle of the display control box 100 as described above, and the middle frame strip 52 is provided with a buckle position for the buckle 10 to be fastened.

[0041] In a specific embodiment, the upper cover 101 is provided with a plurality of the aforementioned buckles 10, such as... Figures 1 to 3 As shown, multiple fasteners 10 are evenly distributed around the top cover 101; the example shown has four on each side. There are multiple fastening positions, corresponding to the number and position of the fasteners 10. Figure 6 As shown, each of the fastening positions includes a fastening groove or hook 83; the groove wall of the fastening groove has an inner groove carved into the outer ear; the example shown is the fastening groove 83. Figure 2 and Figure 6 As shown, the opening of the groove 83 faces the LED display screen, and the extension direction of the groove wall of the groove 83 is opposite to the extension direction of the buckle to form an interlocking structure. The buckle of each upper fastener 11 can be inserted into and locked into the inner groove. The groove 83, for example, has an extended ear integrally formed on the side edge of the middle frame strip 52.

[0042] Furthermore, the box frame also includes a multi-angle rotating lock assembly 91, an upper lock cylinder 107, and a lower lock seat 108; the multi-angle rotating lock assembly 91 is respectively disposed on the left push rod 92 and the right rotating seat 93 on the left and right sides; the left push rod 92 and the right rotating seat 93 are respectively locked, and the upper lock cylinder 107 and the lower lock seat 108 are respectively locked. In addition, the box frame also includes a climbing handle 85; the climbing handle 85 is disposed on the middle frame edge 54 of the box frame, preferably, the climbing handle 85 extends vertically along the main surface or back of the box frame body 50, so that the projection of the climbing handle 85 falls on the box frame body 50, thereby not affecting the hollowing-out effect. The middle frame edge 54 is located between the middle frame strip 52 and the left and right frame edges 51. The width of the middle frame strip 52 is greater than the four frame edges 51 and the two middle frame edges 54.

[0043] It should be noted that this utility model is not limited to the above-described embodiments. Based on the inventive spirit of this utility model, those skilled in the art can make other changes, and these changes made based on the inventive spirit of this utility model should be included within the scope of protection claimed by this utility model.
